Half Mile Dam dam
Half Mile Dam
Half Mile Dam in Leslie, Kentucky, is a privately-owned earth dam with a primary purpose of water supply. Standing at a height of 545 feet and stretching 1300 feet in length, this dam provides a storage capacity of 11,025 acre-feet. Despite not being regulated by the state, Half Mile Dam falls under the jurisdiction of the Mine Safety and Health Administration, ensuring its safety and inspection standards are met. With a high hazard potential, this dam serves as a critical infrastructure for water resource management in the region.
Located in Napier, Half Mile Dam operates without state permitting or inspection. The dam's condition assessment is not available, and there is no emergency action plan in place. Although the dam's risk assessment and management measures are unspecified, its high hazard potential highlights the importance of implementing robust safety protocols. Half Mile Dam plays a crucial role in water supply and tailings management, showcasing the intersection of water resources and climate considerations in dam infrastructure.
Harold Rogers (R) represents the Louisville District where Half Mile Dam is situated, emphasizing the political significance of this water resource structure. As a key component in water supply infrastructure, Half Mile Dam underscores the need for proactive risk assessment and management to ensure the safety and security of surrounding communities. Its large storage capacity and high hazard potential underscore the importance of maintaining and monitoring dams to mitigate potential risks and safeguard water resources in the face of climate variability.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About Half Mile Dam
Where does the data for Half Mile Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
